Liquid and gaseous argon Ar

Argon gas can be reactive at very high temperature with some substances that are not reactive under normal conditions.

Argon gas

Argon gas is a colorless, odorless, non-toxic, non-reactive and non-flammable gas, which is called inert gas. Argon is one of the elements in the periodic table of elements and in the noble gases section. Next, we talk about argon gas and the most important questions about it.

Argon gas is basically a gas that occupies one percent of the atmosphere. As we said, this gas is colorless and odorless, and with the chemical symbol Ar, it is part of the noble gas family. This gas is one of the most useful gases in industrial processes, and it is made by the distillation method.

Argon gas is used as an inert gas at high temperatures, because this gas can be reactive at very high temperatures with some substances that are not reactive under normal conditions. Also, argon can prevent them from entering any kind of chemical reaction.


Argon is colorless, odorless, tasteless and non-toxic. When placed in an electric field, it has a lilac/violet glow.
Argon (Ar) is a noble gas that makes up 0.93% of the Earth’s atmosphere.
This gas provides a motionless and clean environment free of nitrogen and oxygen to melt metals and alloys. In the foundry industry, argon is used to flush out porosity from molten metals to remove defects. This gas is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where materials are usually converted from a non-reactive state to a non-reactive state. become reactive, it is used. For example, argon gas is used in electric graphite furnaces to prevent the graphite from burning. Argon is also used in incandescent lamps, fluorescent lighting, and other gas discharge tubes. This gas creates a distinct blue-green gas laser. Argon is also used in fluorescent glow starters and is often combined with carbon dioxide (CO2), hydrogen (H2), helium (He), or oxygen (O2) to improve the arc characteristics in shielded gas metal arc welding (GMAW and MIG) to reinforce.

Liquid argon is produced industrially by fractional distillation of liquid air. Argon is used as a shielding and inert gas in high temperature industrial and welding processes, in which conditions, usually even non-reactive substances tend to react, so that Argon prevents them from reacting with Avoid any kind of chemicals.

Liquid argon is found in large quantities during air separation. Liquid argon is made by fractional distillation of air, and argon can generally be used in both liquid and gas forms.

The transportation of liquid argon is carried out by refrigerated tankers that have insulation. Liquid argon can be stored and transported in different types, the main ones being Donner tanks, liquid cylinders and cryogenic tanks.

Important factors in determining the price of argon gas

If you want to know the price of argon gas, before you make a purchase, you should know the application, use and other important factors so that you can reach the price of the argon gas capsule. Among these factors, the following can be mentioned:

How much purity do you consider in argon gas?

The producers of argon gas produce different purity of this gas and you should pay attention to this issue when buying, usually people want to buy the highest purity of argon gas, but you can buy argon gases with different purities depending on your needs. provide. Argon gas is usually made in four different types of pure percentage, the purchase of which depends on the application and needs of the customer.

What is the capacity of the argon capsule?

Argon gas is produced in different and suitable capacities, in special cylinders and with different colors. The capacity of these cylinders or capsules usually starts from ten liters and continues until the last limit of its capacity. But it is better to know that the popularity of argon gas capacities in 40 liter sizes is more than other capacities.

Do you intend to buy from the manufacturer or other cases?

The price of argon gas can vary greatly depending on the producer and intermediary. Buying from stores or people who sell this gas privately will definitely cost you more. In addition to the initial purchase cost, you should also consider some cost for the transportation of the argon gas capsule. Finally, we recommend buying directly from the manufacturer, because in some cases you may even see a seventy percent price difference between the manufacturer's price and the middleman's. Parsiagaz provides argon gas at the best price.

The dangers of argon gas

Breathing argon gas

Argon gas is a neutral gas and is the type of gas that causes suffocation. Breathing a large amount of argon gas causes problems such as dizziness, vomiting, nausea, fainting, and finally death in severe cases. Death from argon gas inhalation occurs when a person is unconscious and unable to protect himself from argon gas. When the amount of oxygen in the space reaches a low limit, it can cause a person to die in a few seconds. Dizziness, headache and fatigue also occur due to breathing oxygen gas. It is not possible to say for certain and precisely how much argon gas breathing causes health problems, but if in an environment due to the spread of argon gas, the oxygen in the environment has decreased, especially in closed and limited places, symptoms such as ringing in the ears can occur. , headache, dizziness, nausea and vomiting, sleepiness and unconsciousness. Also, symptoms such as depression of all body senses, confinement and confinement in low oxygen environment can cause death. In the normal state, the air we breathe has 21% oxygen, when the oxygen in the environment reaches 16-12%, breathing and heart rate become faster and muscles start to lose their coordination. People who are suffering from emotional problems begin to observe symptoms such as nausea, vomiting, breathing disorders, abnormal fatigue, collapse, unconsciousness at 10-14% oxygen. And when oxygen reaches less than 6%, all people experience convulsive states and respiratory collapse, and finally the person dies.

Contact with skin or eyes

If argon comes into direct contact with the eyes or skin, it can cause frostbite, injuries and serious injuries, which can turn from mild redness to gangrene if not treated quickly. If argon gas enters your eyes or comes in contact with your skin, it causes freezing in both of them and causes great damage to them.

Fire hazard

Argon capsules can explode under high heat due to high tank pressure.

Environmental effects

Argon normally spreads in the air and does not pose a danger to the life of animals and plants, nor does argon have a harmful effect in aquatic environments.


You can get argon gas with different qualities and in different capacities depending on your needs. Argon gas is sold in different grades. Argon gas is sold by various manufacturers in this field, and you can refer to Parsiagaz company online or in person to find out the terms and prices of argon gas sales.

Normally, most argon gas capsules are filled with argon taken from the atmosphere and the earth’s atmosphere. Usually, the production of argon gas is done by partial distillation, which is basically the same process that is used to produce oxygen gas and nitrogen gas.

The price of liquid argon

The price of argon gas is always calculated according to the specified tariffs, but it is better to know that they use these factors to determine the price of liquid argon:

Other applications of argon gas

Argon gas is one of the common carrier gases in gas chromatography. Argon is used as a carrier gas in plasma etching and ion implantation, and also as an atmospheric blanket in crystal growth.

Argon is also the gas of choice for ICP spectroscopy.

Many counting tubes contain argon gas or a mixture of argon with organic vapors or other gases (e.g. 10% methane in argon).

Argon is one of the main gases for filling incandescent lamps. Argon is usually mixed with nitrogen, krypton and neon in incandescent lamps. Argon is mixed with neon, helium and mercury vapors in phosphor tubes.

The Argon-Oxygen Decarburization (AOD) process is a very common method for improving and refining stainless steel, used in large quantities in both liquid and gaseous forms.

In the pharmaceutical industry, argon is used as a substitute for oxygen at the top of the containers of intravenous drugs to increase the shelf life of these drugs.

Liquid argon is used in cooling surgeries such as surgeries to destroy cancer cells.

Argon is used in atomic absorption spectroscopy as a gas blanket in furnaces with graphite lining.

Argon combined with fluorine and helium is used in excimer laser.

Argon is used as an insulating gas in high-performance double-glazed windows to improve thermal insulation in these windows.

Argon is also used in the iron and steel industry to prevent the oxidation of metal alloys and molten metals. In this industry, argon is also used for degassing and desulfurization of steel and molten iron vats.

Argon is often used mixed with hydrogen as a shielding atmosphere in the heat treatment of certain metals, particularly metals that become sensitive to nitrogen when used in nitrogen-containing atmospheres.

Argon is also used to preserve wine, as argon replaces the heaviest air and prevents the oxidation of the alcoholic solution. As a result, both the quality and shelf life of the opened bottles and barrels increase.

Argon combined with nitrogen is sometimes used to inflate air bags or airbags.

Argon is often used in combination with nitrogen or carbon dioxide to extinguish the fire, because the inert property of this gas prevents it from damaging the equipment during fire extinguishing.

Argon is used in the laboratory as a purifying gas or balancing gas in gas mixtures.
